Can Zoladex cause extreme mood swings & forgetfulness?

My husband had a total prostatectomy 1.5 years ago & now PSA levels started to rise & they gave him 8 weeks of radiation and this hormone oral and now injections- I am finding him becoming mean to me verbally and very forgetful and then blaming me for things he forgot! Does Zoladex have this as side effect or is something else going on? Life with him is getting unbearable at times! & I am a nurse (RN) so very attuned to assessment. Please offer some advice before our marriage is destroyed! Thank you,SD
